As a new type of structure that has gradually developed in the past two decades, the high-altitude corridor structure has been widely used in the construction of multi-story factories with its unique appearance and diverse functions.

[0003] The Chinese utility model patent currently announced as: CN214402111 U discloses a high-altitude earthquake-resistant and decompressive corridor structure, which is provided with a corridor body, and a railing module, a first flat joint component and a second flat joint component arranged on the corridor body; the railing module includes a steel plate, a glass panel arranged on the steel plate, a metal rib, and a fixing part arranged on the metal rib and connected to the glass panel; the corridor body is provided with at least two groups of deformation joints; the first flat joint component and the second flat joint component are both connected to the deformation joints; the first flat joint component includes a first base, a first cover plate arranged on the first base, and a first sliding rod arranged on the first cover plate. The above arrangement solves the problems of the traditional corridor structure being simple, being only overlapped between two buildings by a steel plate frame, and having poor stability.

[0004] The construction of this patented corridor adopts the same erection method as the indoor frame, and no passage openings are reserved. However, most projects have tight deadlines and fast pace, and not having passage openings in the corridor will delay traffic and affect the construction period. Utility Model Content

[0005] The purpose of the utility model is to provide a construction device for overhead door openings of concrete structure corridors of multi-story factory buildings, which solves the problem that an existing high-altitude earthquake-resistant and decompressed corridor structure adopts the same erection method as an indoor frame and does not leave a passage opening. However, most projects have a tight schedule and a fast pace, and the corridor does not have a passage opening, which delays traffic and affects the construction schedule.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a construction device for an overhead door opening of a multi-story factory building concrete structure corridor, comprising a cushion layer and a horizontal scissors brace, wherein the horizontal scissors brace is arranged on the cushion layer, and a plurality of the horizontal scissors braces are fixedly connected to each other to form a frame, and a reserved opening is opened on one side of the frame, and the reserved opening is convenient for vehicles to pass through, and a conversion beam square steel pipe is fixedly connected above the reserved opening, and a crossbeam I-beam is fixedly connected to the square steel pipe of the conversion beam, and a vertical pole is fixedly connected to the upper surface of the crossbeam I-beam, and the vertical pole is arranged at the same height as the upper surface of the horizontal scissors brace.

The horizontal scissors braces are interwoven to form a stable frame structure. On one side of the frame, a reserved opening is specially opened to ensure that vehicles can pass conveniently, which is convenient for the transportation of construction materials and the entry and exit of large equipment, thereby improving construction efficiency. The transfer beam square steel pipe, as an important structural conversion component, can effectively transfer the upper load to the frame below while maintaining the integrity and stability of the structure. On top of the transfer beam square steel pipe, the crossbeam I-beam is fixedly connected. The crossbeam I-beam provides additional support for the entire frame structure with its excellent mechanical properties and load-bearing capacity, and its upper surface is fixedly connected to the vertical poles. These vertical poles are set at the same height as the upper surface of the horizontal scissors brace to form a complete construction platform.

[0008] Further: the upper surface fixing rods of the horizontal scissors brace and the vertical pole are connected with a top support, the top support is fixedly connected with a square steel tube main beam, the square steel tube main beam is fixedly connected with a square steel secondary rib, and the square steel secondary rib is fixedly connected with a wood plywood.
